Dear Dmitry,

Yes, you are right, but this is not what Michael was saying.
What you prove above is that a /24 in IPv6 is a much larger address space
than a /24 in IPv4, which is correct (and obvious to most people, as
this is the very reason for introducing IPv6 in the first place).
Michael said: "an IPv6 /24 and an IPv4 /24 use up the same percentage of
the total address space", which is true. This percentage is 1/2^24 x 100.
Best regards,
Janos
